Description

  • The The present invention relates to a container for irrigating by means Capillarity, which is easy to manufacture and at agricultural facilities and for the use in the household is suitable, for example in flower boxes or Flower pots, the one from a container be fed.
  • background the invention
  • nowadays Two types of devices are known which are made of plastic materials formed in a drizzle irrigation system Find use.
  • A first known watering device is the one called "micro-piping drip." This is the most known and most economical Contraption. In these devices, water circulates through microchannels that reduce the water pressure until a predetermined dribble flow rate is reached. The flow rate is reported outside the device in liters is displayed per hour (calculated by the manufacturer), however used purely as a reference. This is touching from the fact that this reference is different at the outset is from what is displayed and after a continuous use the current decreases until it is completely closed due to of carbonate deposits.
  • A second known device is that called "membrane dripping". This device is based on the principle that the pressure of the water leading to the drizzling supplied will, will fall, when the membrane, which is preferably made of rubber, is pressed, wherein the membrane has a slot on its back, the only one reduced and predetermined amount of water allowed to flow through. to cleaning These types of devices are removable.
  • However, and even though this device is more reliable than the first one is the results are similar due to the high hardness of irrigation water.
  • The Main problem being that of these two types of described devices that is, that they do not provide a constant fluid flow rate. This is touching therefore, that the limestone and magnesium deposits that are on the microchannels attach this completely or partially close, whereby periodic cleaning, preferably with dilute Nitric acid, necessary is.
  • The US 4819375 describes an upwardly open container for plants, a bottom wall, a reservoir adjacent to the container comprises and the one opening at the bottom in conjunction with a membrane in the bottom of the container and a Compartment in operative connection with the reservoir.
  • description the invention
  • task of the container for irrigation by means of capillarity It is the object of the present invention to solve the problems of the prior art to solve the art known devices, while also providing other advantages which will be described below.
  • Of the container the present invention for irrigation by capillarity of the flow rate, required by the plants has a synthetic tissue on that in a carrier is provided, connected to the container for supplying the irrigation fluid to the ground, and with means for controlling the degree of vacuum or negative pressure of the upper portion of the container, and is characterized that he is a bottle, independent from the flowerpot or a similar one Container, that contains the earth and whose lower section is set on the earth, and that the irrigation tissue is a set of fibers.
  • thanks These features become an irrigation device by capillarity which provides a constant and metered irrigation fluid flow rate, independently from the feed pressures. One high hydrostatic pressure is avoided and the irrigation device works by capillarity. It also requires relatively low manufacturing costs compared with the currently used drip systems, so it for the use in hydraulic distribution networks in agricultural Plants and also for Suitable for household purposes, such as in flowerpots or flower boxes on windows. Due to the fact that it is not just one Micro lead deposits, carbonates and similar deposits in the Form of small single sand-like particles along different points of the main channel, whereby the Functioning of the entire system is not affected, with the additional Advantage that the deposits due to the continued operation of the Device are partially eliminated. In addition, the rates of Fibers of synthetic fabric formed to a decay process to prevent caused by microorganisms. In the practice was confirmed that where dripping irrigation supply pipes be used, each one of the drunkards of different Types and models that are available in the market, do not work clean, and completely or partially blocked. This problem is with the new invention Device solved.

  • Also Preferably, the synthetic fabric is nylon. This material can while Its manufacture is easily handled, with a swelling as a result, which considerably increases its capillarity, whereby For example, if an end is placed in a glass of water, a constant siphon-like dribbling is reached at a lower level until the glass is completely empty.
  • According to one embodiment In the invention, the wicks are interposed by the rigid support 0.5 cm and 10 cm, preferably between 1 cm and 2 cm. On this way, when the wicks over the one to be watered area improve the absorption through the soil and through the roots of their function. This does not happen with the before described devices that clogged with the ground very easily become.
  • Preferably are the wicks on the wearer fastened by means of a pin or the like. Thus, in the Trap of high pressures the wicks, which are arranged in the cylinder, with a small one Pins are attached, which prevents them due to pressure pushed out to become.

As a result, a degree of vacuum or a Maintaining the negative pressure level, the liquid prevents it from Outside to flow through the microperforation. This facilitates the slow sucking of air to compensate for the vacuum or vacuum, the through the liquid drain is produced.
  • Also, and although the dripping fully filled with water is there is no dripping off, if this is not put on a flower pot, reducing the flow rate is supplied, which is required by the culture medium.
  • According to one second embodiment The invention consists of the device for controlling the degree of vacuum of the upper portion of the container Wicks of tissue similar to that used in the synthetic fabric. These Wicks are in the side area of the container above the connection level provided the synthetic fabric. As a result, lime closures are avoided and air circulates through the wicks, causing the hydrostatic Pressure due to proximity to the air outlet and the inlet ducts has a minimum.
  • According to one another embodiment The invention consists of the device for controlling the degree of vacuum of the upper portion of the container a conduit which extends through the container, wherein the upper end out of the container protrudes and whose lower end is near the connection level of the synthetic fabric is located. In this way the air is made to reach the slightly upper level, creating a minimal positive hydrostatic pressure is reached, which in some cases negative can be.
  • Preferably is the lower end of the conduit that extends through the container, below the connection level of the watering device and provided in a lower projection of the container.
  • alternative The irrigation container includes the Invention a connection to a irrigation fluid supply network and a vacuum control system. This facilitates the work with larger volumes and containers.
  • According to one another aspect of the invention, this includes an irrigation cycle, the container and is characterized by being a device for refilling the container of the circuit when the liquid level is below a certain level Level falls.
  • Preferably the device for refilling consists of floating floats, valves or the like, which has a low hydrostatic pressure in the Maintain outlet of irrigation tanks.
  • Short description the drawings
  • Around to facilitate the description of all that described above some drawings are attached to schematic and only by non-limiting Example, some practical embodiments of the container according to the invention for Water by capillarity to show in which:

  • description a preferred embodiment
  • Of the Irrigation container by means capillarity the flow rate needed by the plants, such as by drizzle irrigation or The like includes means for supplying the irrigation fluid to the ground by capillarity, wherein the device is connected to the irrigation container. This device for supplying the irrigation fluid to the bottom comprises a set of fibers of a synthetic fabric, which is disposed within a rigid frame attached to the irrigation container is, creating an irrigation tank by means of capillarity which provides a constant liquid flow rate.
  • The Invention is based on the fact that there is no high hydrostatic Pressure that is supplied to the devices, the pressure actually very is low, zero or even negative, causing liquid preferably by capillarity flows.
  • The Device of the invention is on agricultural uses and horticulture applicable.
  • The Flow rates provided by the container of the invention depend from the diameter of the dripping, the type of fiber used and the number of capillary channels it has, as these provide the flow rate, each capillary channel can deliver.
  • The Synthetic tissue consists of a wick that is related with capillarity, Also acts as a stopper, reducing the circulation of water only or nutrient fluids together with any additional fertilizer allows light. This is done at a substantially constant flow rate and becomes less influenced by the pressure differences resulting from the network with to which they are connected.
  • How out 1 As can be seen, the means for delivering the irrigation fluid to the ground comprises a small hollow device 1 of cylindrical, conical or similar shape, in which a thread is provided to the attachment of the wick 2 to facilitate. The device 1 can be extended by adding a hollow collar 3 which is connected to a conventional general distribution line 4 can be adjusted, in an embodiment which is not part of the present invention.
  • The capillaries wore 2 are disposed within the cylindrical device and they are firmly connected to the base. In the case of high pressures, the wicks can 2 be attached with a pin that prevents them from being ejected due to pressure.
  • The used wicks 2 are preferably formed of treated nylon, this nylon providing a swelling which enhances capillarity whereby, when one end is placed on a glass of water at a low level, continuous dribbling is achieved until the glass is completely empty. However, the wicks can 2 also be formed of polyethylene and polyamide.
  • The 2 shows a first embodiment of the irrigation container 5 , made of plastic material, with a microperforation 6 at its side, with a diameter between 0.5-0.7 mm, which is located slightly above the connection level of the improvement tank. As a result, to prevent air from compensating for the vacuum caused by the dispensing of liquid, a certain degree of vacuum is maintained so that no liquid leakage through the perforation is allowed. In the lower section of the container is a wick 2 shown.
  • The 3 shows a second embodiment of an irrigation container 7 , Instead of inserting a microperforation, the container has a small cylindri cal tube 8th slightly above the level of the wick 2 disposed 2 , This tube is also filled with a nylon wick, which achieves the same effects as micro-perforation. This embodiment is advantageous in that lime closures are avoided. In this case, air passes through the wick 8th one.
  • 4 shows a third embodiment of a watering tank 9 with a line 10 to the air inlet, which is located at a level which is higher than the level of the wick 2 , This pipe 10 can be made of plastic material and gets into the container through the stopper 11 introduced. Because the pipe 10 is located above the level at which liquid is supplied, and since the lower portion is in the vicinity of the outlet level of the container, a positive or negative hydrostatic pressure is achieved.
  • The 5 shows a fourth embodiment of a watering tank 12 with an extension 13 in its lower section, eliminating the lower end of the air duct 14 below the wick 2 for the liquid outflow.
  • The 6 shows a container according to the invention 15 for the use of serum on an agricultural or industrial scale, that is, using higher volumes and larger containers containing a lead 16 which is connected to the feed network, the line being a small device 17 includes, which allows an air outlet. In the lower section of the container 15 is a plurality of wicks 2 shown.
  • It It is noted that the dribbling in both agricultural Facilities as well as in the domestic Environment can be used, such as in flowerpots or flower boxes on windows.
  • In the case where he is in flowerpots is used, reserves the irrigation container according to the invention by means of capillarity optimum soil moisture level without the need to flood it with water or expel the air, which is so necessary is for the roots of plants. In addition, it has the advantage that liquid extremely rarely on the lower section of the flowerpots or flower boxes flows. When this occurs, it is due to an inappropriate composition of the cultivation soil and it is pointed out the most suitable To use soil. The irrigation reservoir used in flower pots can be placed on a plastic base of conical shape, on which the lower section of the container fits. Consequently, if the bottle or the container for refilling is removed, the carrier remains above the Flowerpot, reducing the presence of moisture or soil at the lower portion of the container avoided, which may fall into the ground or the ground.
  • Of the Plug, which is screwed through either the upper section of the container or pressed in can be the hydration. When checking the Container, can vacuum or vacuum be eliminated, and even if appropriate, Is it possible, an additional irrigation only by loosening to provide the plug. The differences in consumption are included each flowerpot very different or very different, depending on the size of the flower pot, the type and size of the plant and the season, creating containers comprising the devices according to the present invention Invention must be supplied in different sizes. If once the appropriate size has been selected, guarantee the containers a continuous irrigation for some days or weeks without the need for refilling.
  • The suitable composition of the culture soil or the culture soil along with its structure, its content of peat and organic Material is essential to an adequate level of humidity too achieve and facilitate the development of plants. Usually is the one for flower pots in the trade available Soil perfectly suited to an adequate water-to-air balance to reach.
  • Independent of The aim of the invention are the materials used for the manufacture the parts containing the described container for irrigation means capillarity form, as well as the formulas and sizes of the same and all the extra Details that may be added can be replaceable by others that are technically equivalent as long as they are not affect their essential nature or to depart from the scope defined by the claims appended hereto is.
